http://ocs.ciemat.es/EPS2019ABS/pdf/I1.401.pdfIn the source regions of the Type III solar bursts, energetic electron beams are accelerated in the low solar corona during flares. Observations show that such beams can propagate in the solar wind up to distances around 1 AU and beyond, generating Langmuir turbulence that emits specific electromagnetic radiation. The...

http://ocs.ciemat.es/EPS2019ABS/pdf/I1.402.pdfJets emanating from active galaxies are among the most powerful particle accelerators in the universe. They shine across the entire electromagnetic spectrum, and are candidate sources of ultrahigh-energy cosmic rays. Yet, the dominant mechanisms responsible for particle acceleration in these systems are not well...

Collisionless shocks are ubiquitous in the Universe and play an important role in the slow down of plasma flows, magnetic field generation/amplification, and particle acceleration. Depending on the plasma conditions, different plasma processes are believed to mediate shock formation and particle injection, however,...

The interactions of fast-streaming, magnetized plasmas can result in a wide range of fundamental plasma physics processes such as the formation of MHD shocks, magnetic turbulence, reconnection and wave-particle interactions. We present experiments from a versatile platform, where supersonic plasma flows generated by the...

Efficient particle acceleration is produced in association with solar flares. These particles play a major role in the active Sun because they contain a large amount of the magnetic energy released during flares. Energetic electrons and ions interact with the solar atmosphere and produce high-energy X-rays and -rays....

The complex interaction of the magnetic field with matter is the key to some of the most puzzling observed phenomena at multiple scales across the universe, from tokamak plasma confinement experiments in the laboratory to the filamentary structure of the interstellar medium. King among these is the phenomenon of...

The solar wind is a supersonic turbulent flow that spreads out radially form the Sun. Several spacecrafts explored different regions of the Heliosphere and provide us in-situ data of plasma and electromagnetic fluctuations from daily to sub-second scales. The solar wind can be though as a wind tunnel in which...

In 1958, Eugene Parker first predicted the existence of the supersonic solar wind [1], which was subsequently verified by early spacecraft missions [2]. He also theorized how this solar wind interacts with the dynamo-generated magnetic field of the Sun - carrying the magnetic field lines away from the star, while their...

Over the last decades the availability of continuous observations of the solar atmosphere (the corona) from space allowed to study in great details solar eruptions, namely Coronal Mass Ejections (CMEs; see review by Webb & Howard 2012). For major CMEs it was shown (Vourlidas et al. 2003; Ontiveros & Vourlidas 2009)...

A charged particle moving through a medium emits Cherenkov radiation when its velocity exceeds the phase velocity of light in that medium. Since light in vacuum is usually assumed to move at the universal speed c, causality appears to preclude vacuum Cherenkov radiation (VCR). Under the influence of a strong...

Plasma turbulence has been investigated using unprecedented high-resolution ion velocity distribution measurements by the Magnetospheric Multiscale mission (MMS) in the Earth's magnetosheath. This novel observation of a highly structured particle distribution suggests a cascadelike process in velocity space [1], as...

We present the first measurement of nonlocal electron transport on Warm Dense Matter (WDM) [1]. The experiment was carried out at the OMEGA laser facility, where we used 15 beams drove a fast compression wave in low-density CH foam generating WDM conditions. We combined multiple independent diagnostics including...

Magnetic dipole fields have exellent confinement properties for charged particle ensembles with an arbitrary degree of neutrality. One idea to create a magnetized low-energy electron-positron pair plasma pursued by the APEX/PAX collaboration relies on the initial formation of a non-neutral plasma in the confining...

Nonlinear synchronisation is a key process in wave-particle interaction [1], responsible for Landau damping as well as for the amplification in devices like traveling wave tubes and gyrotrons [2]. We investigate it using the finite-N approach from a self-consistent hamiltonian formalism [3]. This description is combined...

In laser plasmas, as well as in solar and stellar winds, ions and electrons can have comparable energies and strongly anisotropic velocity distributions. Under those conditions both fractions of a collisionless plasma can make a significant contribution to the development of the Weibeltype instability and the subsequent...

Large amplitude, turbulent Alfvénic fluctuations have been commonly observed in the solar wind since the first in-situ measurements. An important but still unexplained property of such nonlinear fluctuations seen typically in the fastest streams is that, despite the large excursion of the magnetic field fluctuations,...

One of the most eminent unsolved problems in space plasma physics is the nature of turbulent energy dissipation at small spatial scales, which is thought to explain the heating of the heliospheric plasma that has been consistently observed through space craft measurements[1].

Rapidly rotating neutrons stars and black holes are the central engines of some of the most extreme astrophysical phenomena such as gamma-ray bursts, pulsars, X-ray binaries, binary mergers or active galactic nuclei.

Understanding the transport of charged particles in the Galaxy is fundamental to solve the mystery of the origin of Galactic cosmic rays (CR) and to asses their role in several Galactic processes. Recent results from direct experiments, especially AMS-02 and PAMELA, are revealing a fine structure in the CR spectrum...

The recently developed theory of the Spectral Web [1, 2] is a method to compute the full complex spectrum of stationary plasmas together with a connecting structure. This permits to consider the enormous diversity of MHD waves and instabilities of rotating tokamaks and astrophysical plasmas from a single unifying view...

Cosmic rays are charged particles, moving at relativistic speeds after being accelerated through interaction with astrophysical shocks. This process, known as diffusive shock accleration, or Fermi acceleration, involves the particle repeatedly crossing the shock, picking up speed each time it is reflecte by the local...

The properties of magnetohydrodynamic (MHD) turbulence have significant implications for astrophysical phenomena like cosmic ray scattering. We study properties of MHD modes by decomposing data of MHD simulations into linear MHD eigenmodes - namely the Alfvén, slow, and fast modes. Some earlier studies have shown the...

Observations recorded from NASA's Van Allen Probes have revealed the prevalence of a broad spectrum of Alfvénic field fluctuations in the inner magnetosphere. The properties of these waves in the inhomogeneous plasma of his region of near-Earth space give rise to a number of resonant and non-resonant interactions...

Turbulent fast magnetic reconnection can be an important mechanism for accelerating particles to relativistic velocities and produce very-high-energy (gamma-ray and neutrino) emission in the magnetized regions of galactic and extragalactic black hole sources.

Astrophysical plasmas are ubiquitous and differ from laboratory plasmas in key aspects. They are typically cold (k_B T<<m_e c^2), collisionless, and usually contain relativistic sub-populations. To study the evolution of such plasmas, it is necessary to employ a fully kinetic treatment.
